我们提出了一种算法来构建一组接口来分离多值卷数据集的连接组件。虽然每个单一界面是一个流形三角形网格，但两个或多个界面可以沿着它们的共同边界一致地连接，即没有t形结或间隙。与以前的工作相比，我们的算法在提取接口之前对体进行分类并去除拓扑模糊性。这不仅允许一个简单而稳定的提取算法，而且还使得包含用户约束成为可能。
We propose an algorithm to construct a set of interfaces that separate the connected components of a multi-valued volume dataset. While each single interface is a manifold triangle mesh, two or more interfaces may join consistently along their common boundaries, i.e. there are no T-junctions or gaps. In contrast to previous work, our algorithm classifies and removes the topological ambiguities from the volume before extracting the interfaces. This not only allows for a simple and stable extraction algorithm, but also makes it possible to include user constraints.
